Ohhh goody! I know what I am buying off my roomate tonight .

Thanks for the info! I'd be interested in any production chipping you get into, thats for sure .

I don't know about going into production or not. Tell me what you want and I'll burn you a chip for $25, and tell you where to get the socket that I use. Or I could order a bunch of those if you guys are going to want any changes made.

Jmauld:

You could start paying for the site that way

I haven't seen one, but if you find one, let me know.

i was wondering why mitsu made some eprom ecu and some other non eprom???

some times even in the same year there was eprom and non eprom. why?

no idea....

Hmm, sounds like a plan to me . All I would really like is to set the idle a bit higher ( I just can't get used to seeing a 4 cylinder idle below 1000 rpm ), and some small tweaks to stuff like timing .

What sort of things can you do the ECU? Would I have to find you a blank chip as well as the ZIF socket? I can surely do these things for a re-burned chip .

I have the chips. I just need to find an eraser to clean them. Once I get back from my vacation next week, I'll start hunting for a good one.

So far, I can adjust the following:
WOT timing (still testing this)
rev limiter
idle speed

I'm learning stuff as I personally want to change things on my own car, so if the WOT timing works, I'm going to start playing with the timing when you first go to WOT. To hopefully help with engine response.

Then the fuel maps. Which seem to be extremely complex.

jason:

is the timming affected by the boost? or is it just with the amount of air beeing detected by the maf, the rpm , and tps.

Indirectly it is. If you turn up the boost to the point of knock, then it is pulled back.

Otherwise it's based on airflow, airtemp, rpm, tps, ...

ok, and air temp, air flow and rpm will determine boost i belive, amount of air going throught at what temp and the rpm wil determine the back pressure creating the boost.

Cool! I joined the yahoo group DSM-ECU to attempt to understand better, but it looks like it will take a while . I'd be interested in a more aggressive stock setup, like the GVR4 or something like that. I do not have exel so I could not check the graphs in the archives of the site, but I think I saw the GVR code there...as well as possibly some TMO stuff?

yeah, talking about exel.... i keep getting "#name!" as a result to the formulas HEX2DEC(XY)m is there any option i have to setup in order to work in hexadecimal files?

There's a package that you need to install to get the hex2dec to work. I don't know what package it is, but if you do a help search for hex2dec it will tell you.

There shouldn't be any TMO code on the site. Maybe some analysis of what he's done, but none of his exact code.

i just made those two little graphs, with the data from your board jason, and i was also looking over ther if somebody knew what was making the ecu taking one table or the other. I know its what we discussed in the above posts, but on the chip do we know where are these adresses??

Im still looking.... maybe im asking too much stupid question today
